CAR-COUPUNG.

vSPECIFICATION forming part ofretters Patent No. 263,995, dated september 5, 1882.

Application filed July 13, 1882.

To all whom it may concern:

Beit known that I, JOHN Q. THOMAS, of Longview, in the county ofOhristian and State of Kentucky, have invented certain new and useful Improvements in Oar-Couplings; and I do hereby declare that the followingv is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, refe. ence beinghad to the accompanying drawings, which form a part ofthis specification.

Figure 1 is a perspective view. Fig. 2 is a longitudinal vertical sectional view, and Fig. 3 is a horizontal sectional view.

Corresponding parts in the several gures are denoted by like letters of reference.

This invention relates to automatic vor selfacting car-couplings; and it consists in certain improvements in the construction ofthe same, which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, A represents the draw-head, which consists of top and bottom plates, B O, held apart or spaced by lianges D and connected by bolts E. The flanges F at the front end ofthe draw-head are made diverging from the mouth or opening G, which is provided for the reception of the coupling hook or link.

Upon vertical bolts H H, rear of and at the sides of the mouth or opening G, are pivoted a pair of tongues, I, the outer sides ot' which have recesses J to receive the ends ot'arms or bolts K, which are lpivoted in said recesses.

The said bolts K extend through the side flanges, D, of the draw-head, where they are provided with heads L and eyes M.

Springs N are coiled upon the bolts K bev tween the tlanges D and tongues I, which lat- (No model.)

ter are thereby forced in an inward direction toward each other.

A central vertical opening, O, is provided in the draw-head for the reception of a couplingpin, P, upon which is pivoted the couplinghook Q, the projecting end ot' which has an arrowhead, R, to engage the spring-tongues I of the next adjoining draw-head.

The sides ot' the draw-head are provided with brackets S, to which are, pivoted levers T, the lower ends of which work in the eyes M ot' the bolts K. The upper ends of said levers are connected by ropes or chains U with a vertical shaft, V, mounted in suitable bearings and extending to thepplatf'orm or top of the car, where it is provided with a crank or handle. By revolving said shat't the chains U ave wound upon it, thus operating the levers T and throwing the tongues I out of cngagement with the coupling-hook.

I claim and desire to secure by Letters Patent ofthe United States- The draw-head A, consisting of plates B O and flanges D E, and provided with laterallyprojecting brackets S, in combination with the pivoted tongues I, bolts K, having heads L and eyes M, springs N, vertical levers T, vertical shaft V, connecting-chains U, and the pivoted coupling-hook Q, having arrowhead R, all arranged and operating as herein shown and specified.

In testimony that I claim the foregoing ns my own I have hereto affixed my signature in presence of two witnesses.

JOHN QUARLES THOMAS.
